| 摘要: |
| 气体绝缘组合电器(GIS)特高频局部放电信号为上升沿和脉宽均为纳秒级的陡脉冲信号,它是表征设备绝缘状态的重要特征量。为在线实时监测和信号处理,提出一种基于LabVIEW的文件数据融合管理的方法,将文件管理和数据库管理的优势相融合,构成一种适合陡脉冲信号数据存储的文件数据融合管理系统。介绍了GIS在线监测系统后,叙述了数据管理的要求、常用方法,数据融合管理系统的数据库操作、陡脉冲局部放电波形数据的保存、数据库信息查询等关键技术。实践表明,所构建的文件数据融合管理系统能有效地管理大量的陡脉冲局部放电监测数据。 |

| Abstract: |
| Ultra high frequency PD(Partial Discharge) signals reflect the insulation status of GIS(Gas Insulated Switchgear) devices effectively,which are steep pulses with rising edge and pulse width in nanoseconds.A data fusion management method based on LabVIEW is proposed for online monitoring and signal processing,which integrates file management and database management together to construct a data-file fusion management system for steep pulse signal storage.Key techniques are introduced,such as the requirements and ways of data management,the database operations,the PD wave data storage,the database query and so on.Practices show that the data-file fusion management system can effectively manage the massive monitored PD data. |
